摘　　要：主要探讨铁尾矿砂在普通干混抹灰砂浆中的应用,主要研究铁尾矿砂取代比例对普通干混抹灰砂浆的性能(表观密度、保水率、黏结强度、抗压强度)的影响;并利用SEM对其进行微观分析。表明结果:在满足普通干混抹灰砂浆工作性能及力学性能条件下,铁尾矿砂可以不同比例取代人工砂或河砂。It is discussed for the application of iron tailings in ordinary dry mixed plastering mortar.The effect of iron tailings replacement ratio on the performance(apparent density,water retention,compressive strength,bond strength)of ordinary dry mixed plastering mortar was studied,and the microcosmic analysis was carried out by using SEM.Results show that under the condition of satisfying the working and mechanical properties of ordinary dry-mixed plastering mortar,iron tailings can replace artificial sand or river sand in different proportions.
